i bought a cpo jku mountain and was offered the lifetime warranty as the factory warranty was nearly expired i dont remember how much it was but i took the dealer up on the deal it had k on it when i bought it in late in dec of my transmission started slipping in jan before i had a chance to work on it my tranny died on me while i was hours from home the warranty covered my towing home and the new tranny the warranty almost paid for itself with the tranny alone so it was well worth it for me even though i traded that jeep in for my rubicon a couple months later in april
